[QUOTE="robertjordan, post: 4500362, member: 464439"] [h2]Homework Statement [/h2] Using the Bohr model of the atom, compute the energy in eV of the one electron in Li[SUP]2+[/SUP]. [h2]Homework Equations[/h2] [itex]E_n=\frac{m\cdot e^4 \cdot z^2}{2n^2 \cdot \hbar^2}[/itex] Where m= mass of electron, z= atomic number, e= charge of an electron, n is the energy level. ^ I think those are the right meanings of the variables... [h2]The Attempt at a Solution[/h2] plugging in 1 for n, 3 for z, 9.11*10^-31 kg for m, -1.602*10^-19 Coulombs for e, and 1.054572×10^-34 J*s for h, we get E_1= ((9.11*10^-31 kg))*((-1.602*10^-19 C)^4)*(3^2)/(2(1.054572×10^-34 J s)^2) = 2.428×10^-37 s^6A^4/(kg m^4) (second to the 6 amperes to the fourth per kilogram meter to the fourth). This clearly doesn't seem right. What am I doing wrong? I need help... [/QUOTE]
